The Levenhuk Ra R80 ED Doublet Carbon OTA is an 80mm short-focus apochromatic refractor with extra-low dispersion optics. It features a high aperture and wide field of view, but its main advantage is that it effectively reduces chromatism and, therefore, it transmits a very clear image. Due to fully multi-coated optics, the telescope renders highly contrast and bright images. This optical tube is a great choice for visual observations and astrophotography.

The body is made of carbon fiber that is lighter than aluminum. What's more, the OTA's thermo stabilization is faster, as its body doesn't change inside due to temperature changes, and only the optics and the air inside should "cool down". This allows you to start observing faster as well as the quick-release thumbscrew. The OTA features a 2" dual-speed Crayford focuser. It provides smooth sharpness adjustment, no backlash, and holds even heavy optical accessories securely.

The Levenhuk Ra R80 ED Doublet Carbon OTA is well suited for use in the countryside due to its compact size, and light weight as well as being mobile and easy to carry. In addition, the kit includes robust aluminum case.

Please note: Mount, tripod, and optical accessories are not included.

what is the net weigth of this scope compared to non-carbon version? Also, does it use the same type of glass? Thanks
Customer service:
Dear Roman, thank you for your inquiry. Yes, both models come with fully multi-coated ED glass. Levenhuk Ra R80 ED Doublet OTA will be a little bit havier.
